When an infant is exposed to smoke, they are less likely to be able to wake themselves up if there is a breathing problem. The greater the smoke to which the infants are exposed, the greater the risk that the baby will not be able to rouse herself.

Although the study in question was too small to provide definitive information, it is still important to avoid smoking both for your health, and for that of your baby.

The exact mechanism that causes SIDS has not yet been discovered. Researchers believe it may be a function of genetic anomalies of the brain or perhaps even a heart condition. Here are the things you can do to help avoid SIDS:

Stop smoking, ideally before you become pregnant

Do not use illegal drugs while pregnant

Eliminate or minimize caffeine use while pregnant

Keep your baby away from smoke

Put your baby to sleep on her back, on a firm surface

Your baby should sleep in a slightly cool room

Breastfeed your baby

Unfortunately, there is no certain way to prevent deaths from SIDS at this time. Be aware of the factors you can affect, particularly smoking.
